Thanks for answering, piston marks, free valves, nothing to do, it is still the same today in the same way that they are mounted at the old school, but nothing with the engine, it does not start, I go tomorrow with the compression in case I double any valve, verify the VVT, that when they do not have lubrication or are covered with old oil they give problems as if I did not have compression the engine but verify it and clean it Complete cams will see to see tomorrow.
